Chuck is stuck and will not turn
I went to use my drill the other day and when I went to put a bit in the teeth, the chuck would not move. I could not get the teeth to move at all, and the chuck would not turn. I thought maybe it was just stuck and thought about putting something in there to loosen things up, but my father-in-law was afraid it might get into the electrical parts. Any information on how to get this unstuck would be helpful. Thanks!
